The Sun-safe Habits Intervention and Education (SHINE) Phase 3 trial for Skin Cancer prevention reached primary completion on 2025-07-15, with 2,223 participants enrolled.
Background
Skin cancer remains a significant public health concern, with a substantial portion of lifetime sun exposure occurring during childhood and adolescence. Establishing sun-safe habits early is crucial for long-term prevention. Adolescents, particularly high school students, are a key demographic for intervention due to developing independence and social influences that can impact sun protection behaviors and intentional tanning. Effective educational interventions are needed to promote protective behaviors and reduce risky sun exposure, thereby lowering future skin cancer risk. This study aimed to evaluate an intervention designed to address these behaviors specifically within a high school setting.
Trial design
This completed study, designated as Phase 3, enrolled 2,223 participants. The trial investigated conditions including Skin Cancer and Adolescents. The study's purpose was to determine the efficacy of the Sun-safe Habits Intervention and Education (SHINE) intervention in improving sun protection use and decreasing intentional tanning among high school students. The trial design involved randomizing 30 schools, with approximately half assigned to the SHINE intervention and the other half assigned to standard education. Following randomization and a baseline assessment, each school received two in-class intervention sessions delivered by an interventionist. Follow-up assessments were planned for one month and 3-4 months post-intervention.
What this means
The primary completion of the Sun-safe Habits Intervention and Education (SHINE) Phase 3 trial signifies that data collection for the main objectives has concluded. While specific results are not yet available, the trial's completion indicates progress in evaluating an intervention aimed at fostering sun-safe behaviors and reducing intentional tanning among high school students. The findings from this study are anticipated to provide valuable insights into effective strategies for adolescent skin cancer prevention, potentially informing future public health campaigns and educational programs.
